Many smartphone owners often wonder how to turn on the infrared port on the Xiaomi Redmi Note 8 to use the device as a universal control panel. It is a really convenient feature that allows you to get rid of many remotes from the TV, air conditioning and other household appliances. However, there is a common misconception about the very presence of this module in certain models of devices.
In this article, we will discuss in detail the specifications of your gadget and explain why you can not find the appropriate setting in the menu.You will learn how to check the presence of an IR emitter on the case, what alternative ways to control equipment exist and how to properly configure the Mi Remote application for operation over a Wi-Fi network. This will save you time and nerves when trying to activate non-existent equipment.
Checking the presence of an IR module on the device body
The first and most important step before trying to program activate any feature is to physically check the device. In the case of the Redmi Note 8 model released in 2019, the situation is ambiguous for the untrained user. The infrared port is a small black window, usually located on the top end of the smartphone next to the noise reduction microphone or headphone jack.
Carefully examine the top of your phone in good light. If you see a small black dot other than the microphone hole, you are lucky that the module is present. However, in most regional versions of the Xiaomi Redmi Note 8, the manufacturer has decided to abandon the installation of this component in order to reduce costs and save interior space.
- 🔍 Find the top end of your smartphone and wipe it from dust for a better view.
- 📱 Compare your device with the official renders on the manufacturer’s website.
- ⚙️ Start the Mi Remote app – it will report the lack of equipment.
- 🌐 Check the specification of your particular model on the package or in the box.
⚠️ Note: If there is no black infrared diode on the upper end of the case, no software methods, firmware or third-party applications will make it work, since there is nothing to physically emit a signal.
The lack of a visible module does not mean that the phone is useless for controlling equipment. Modern technology allows you to use other communication protocols that often work even more stable and faster than an outdated infrared signal.
Why the IR port on the Redmi Note 8 is not working
The main reason why users can’t turn on the infrared port on the Xiaomi Redmi Note 8 is because of the hardware limitations of the model. Unlike the flagship series or some of the later Redmi Note series models, this version simply lacks the necessary hardware module.
The Mi Remote system application, which is pre-installed in the MIUI shell, automatically diagnoses when it starts up, and if the sensor is not detected, the application will either fail to open or immediately give an error that the device does not support IR control. Attempts to download alternative programs from Google Play will also fail, since they also rely on the presence of a physical emitter.
It’s not a defect or a defect, though, as Xiaomi engineers deliberately took this step to offer a more competitive price in the budget smartphone market. The IR remote is gradually becoming the preserve of more expensive models or devices specifically targeting the Chinese market, where IR-based control of appliances is still extremely popular.
Can I use the IR port on my own?
Don't worry about not having this feature, because IR ports have been replaced by more advanced technologies, such as Wi-Fi and Bluetooth, that allow you to control your technology not only in line of sight, but from anywhere in the world where you have access to the Internet.
Alternative: Management over Wi-Fi and Cloud Services
If your Redmi Note 8 doesn't have an infrared port, it doesn't mean you can't control your TV or console with your smartphone. Most of today's TVs released after 2015 are network-based, and your phone and TV must be connected to the same Wi-Fi network.
To implement this feature, you will need the Mi Remote app (for Xiaomi equipment) or third-party solutions such as Google Home, Android TV Remote Control or apps from TV manufacturers (Samsung SmartThings, LG TV Plus), which use a network protocol to transmit commands, which is often even more convenient, since it does not require you to point the phone directly to the screen.
| Type of connection | Equipment required | Radio of action | Do you need direct visibility? |
|---|---|---|---|
| Infrared port (IR) | Built-in IR module | Up to 10 meters. | I'll be sure. |
| Wi-Fi (Network) | Router, Smart TV | Up to 50 metres (indoors) | Not required |
| Bluetooth | BT-TV-module | Up to 15 meters. | Not required |
| USB-adapter | External IR whistle | Depends on the adapter. | Depends on the adapter. |
It usually takes a couple of minutes to set up this connection, and you have to download the app from the Play Market, search for devices on the local network, and confirm the pairing on the TV screen, and then your smartphone becomes a full-fledged touchpad.
💡
To control older TVs without a Smart TV, you can purchase an external IR transmitter that connects through a USB (Type-C) connector on a smartphone, which often has its own applications and emulates the operation of the built-in port.
Set up Mi Remote app for Smart TV
Since there is no built-in infrared port on the Xiaomi Redmi Note 8, we will focus on setting up the software remote, which is a standard solution that is already in your phone or easy to download, and is ideal for network-enabled hardware.
To start, make sure your smartphone and TV are connected to the same wireless network. Open the Mi Remote app (or Remote). If this is the first run, the system will suggest you choose the type of device. Select TV and find your manufacturer's brand in the list.
- 📡 Make sure the network control function is enabled on the TV (often called the "Network Control" feature). DLNA or remote control).
- 🔗 In the application, click "Add remote" and select a search over the network, not IR.
- ✅ Follow the instructions on the screen to confirm device pairing.
- 📺 After setting up, you will be able to switch channels, adjust volume and run applications.
⚠️ Note: Wi-Fi control may have a slight delay between the press of a button on the screen and the response of the TV. This is normal for network protocols, as opposed to instant IR port response.
The functionality of the network remote is often wider than that of a regular IR. You can not only switch channels, but also display the image from the phone to the screen (Cast function), use the keyboard to enter text in YouTube search, and even broadcast sound through the phone headphones so as not to disturb others.
☑️ Setup Mi Remote
Use of third-party applications for management
If the standard Xiaomi app for some reason does not see your TV or is unstable, you should pay attention to third-party developments. Android ecosystem offers many tools that can bypass the limitations of standard software and offer more flexible settings.
One of the most popular solutions is the Google Home app, which automatically scans the network for compatible devices, and if you have an Android TV, you'll have the deepest, most integrated control over the service, and you'll be able to not only switch channels, but also completely duplicate the screen of your smartphone.
For owners of Samsung, LG or Sony, the best way to use proprietary utilities is to use Samsung SmartThings or LG TV Plus, which are developed directly by engineers from the TV manufacturers, so they guarantee support for all the specific features of your model that may not be available in universal remotes.
💡
Third-party apps often have a more frequent update cycle and are better at supporting new TV models than embedded system solutions.
When installing third-party software, pay attention to the permissions requested. The remote only requires access to the local network. If the program requires access to contacts, microphone or geolocation without an obvious need, this can be a sign of bad faith of the developer.
Frequent problems and methods of their solution
Even when using Wi-Fi management, users may encounter difficulties, and it often happens that the phone stops seeing the TV after updating the router or changing the network security settings. In such cases, you do not need to panic, most problems are solved with simple actions.
One common reason is the splitting of Wi-Fi frequencies. If your router distributes a network at 2.4 GHz and 5 GHz with different names (SSID), make sure that both the phone and the TV are connected to the same frequency. Some older TV models simply don't see the device on the 5 GHz network.
It's also worth checking the firewall settings on the router. AP Isolation prevents devices within the LAN from communicating with each other. If this feature is enabled, the phone won't physically be able to send a command to the TV, even if they're connected to the same router.
⚠️ Note: After resetting the router or TV settings, the pairing procedure will have to be reset. Save the passwords from the Wi-Fi network to avoid losing access to control.
If nothing works, try rebooting both devices at the same time, turn off the TV for 30 seconds, restart the smartphone, and try to find the device again, which solves the cache problems of network services in 90% of cases.
What to do if the remote is running with a delay?
Conclusion and final recommendations
In summary, it is safe to say that it is impossible to include a classic infrared port on the Xiaomi Redmi Note 8 due to its physical absence from this model. Trying to find hidden settings or install “magic” programs will not lead to the desired result, since hardware cannot be created software.
However, modern technology offers an excellent alternative in the form of control over Wi-Fi. It is even more functional solution that allows you to control equipment from anywhere in the apartment and use the advanced capabilities of Smart TV.
Use the Mi Remote app or proven analogues from the Play Market to interact with your TV comfortably. Proper network setting and understanding of the principles of modern communication protocols will allow you to forget about the inconvenience of not having an infrared port.
